Ukugalela iikhabhoni kunye nokugalela i-nitriding

Yintoni iCarburizing kunye neNitriding

I-Vacuum Carburizing ene-Acetylene (AvaC)

Inkqubo ye-AvaC vacuum carburizing yitekhnoloji esebenzisa i-acetylene ukuphelisa ingxaki yokwakheka kwe-soot kunye ne-tar eyaziwayo ukuba ivela kwi-propane, ngelixa inyusa kakhulu amandla e-carburizing nokuba kungaboni okanye kudlula kwimingxunya.

Enye yezona nzuzo zibalulekileyo zenkqubo ye-AvaC kukufumaneka kwekhabhoni eninzi, okuqinisekisa ukuba i-carburizing iyafana kakhulu nakwiijiyometri ezintsonkothileyo kunye nobunzima bomthwalo obuphezulu kakhulu. Inkqubo ye-AvaC ibandakanya ukufakwa kwe-acetylene (boost) kunye negesi engathathi cala, efana ne-nitrogen, ukuze isasazeke. Ngexesha lokufakwa kwe-boost, i-acetylene iya kwahluka kuphela xa idibene neendawo ezinesinyithi esipheleleyo nto leyo evumela ukuba i-carburizing ifane.

Eyona nzuzo imangalisayo kwi-AvaC inokufumaneka xa iigesi ezahlukeneyo ze-hydrocarbon ze-carburizing ezinoxinzelelo oluphantsi zivavanywa amandla azo okungena kwimingxunya emincinci, emide, nengaboniyo. I-vacuum carburizing ene-acetylene iphumela kwisiphumo esipheleleyo se-carburizing kulo lonke ubude bembobo kuba i-acetylene inamandla e-carburizing ahluke ngokupheleleyo kune-propane okanye i-ethylene.

Iingenelo zenkqubo ye-AvaC:

Amandla okucima ahlukeneyo nge-helium, i-nitrogen, iigesi ezixutyiweyo, okanye ioyile

Iingenelo ngaphezu kwezitofu zomoya:

Indawo yokusebenza engcono enoyilo olufana nodonga olubandayo, olubonelela ngobushushu obuphantsi beqokobhe

Akukho zigqubuthelo zokukhupha umoya ezibizayo okanye iinqwaba ezifunekayo

Ukuqalisa nokuvala ngokukhawuleza

Akukho mfuneko yeejenereyitha zegesi ze-endothermic

Izitofu zokucima igesi zifuna indawo encinci yomgangatho kwaye azidingi kuhlamba emva kokususa iioyile zokucima igesi

Akukho mfuneko yemingxuma okanye isiseko esikhethekileyo

Ukuqhuba ngekhabhoni

I-Carbonitriding yinkqubo yokuqina kwetyala efana ne-carburizing, kunye nokongezwa kwe-nitrogen, esetyenziselwa ukwandisa ukumelana nokuguguleka kunye nokuqina komphezulu. Xa kuthelekiswa ne-carburizing, ukusasazwa kwe-carbon kunye ne-nitrogen kwandisa ukuqina kwe-carbon ecacileyo kunye neentsimbi ze-alloy eziphantsi.

Izicelo eziqhelekileyo ziquka:iigiya kunye neeshaftiiipistoniirola kunye neebheringiiilevers kwiinkqubo ze-hydraulic, pneumatic kunye ne-mechanical actuated.

Inkqubo ye-carbonitriding enoxinzelelo oluphantsi (i-AvaC-N) isebenzisa i-acetylene kunye ne-ammonia. Njengokugalela i-carburizing, inxalenye ephumayo inesikhewu esiqinileyo nesinganyangekiyo. Nangona kunjalo, ngokungafaniyo ne-AvaC carburizing, ubunzulu be-nitrogen kunye ne-carbon case buphakathi kwe-0.003″ kunye ne-0.030″. Ekubeni i-nitrogen yonyusa ukuqina kwentsimbi, le nkqubo ivelisa iindawo ezinobunzima obandayo ngaphakathi kobunzulu besikhewu obubonisiweyo. Ekubeni ukugalela i-carbonitriding kwenziwa kumaqondo obushushu aphantsi kancinci kune-carburizing, ikwanciphisa ukugqwetheka okuvela ekucimeni.

Ukukhupha iNitriding kunye neNitrocarburizing

I-nitriding yinkqubo yokuqinisa i-case esasaza i-nitrogen kumphezulu wesinyithi, uninzi lwazo ludla ngokuba ziintsimbi ezine-carbon ephantsi, ezine-alloy ephantsi. Ikwasetyenziswa kwiintsimbi eziphakathi nezine-carbon ephezulu, i-titanium, i-aluminium kunye ne-molybdenum.

I-Nitrocarburizing yindlela eyahlukileyo yenkqubo ye-nitriding apho zombini i-nitrogen kunye ne-carbon zisasazeka khona kumphezulu wenxalenye. Iingenelo zenkqubo ziquka ukukwazi ukuqinisa izinto kumaqondo obushushu aphantsi okunciphisa ukugqwetheka. Ikwabiza kancinci xa ithelekiswa ne-carburizing kunye nezinye iinkqubo zokuqinisa ii-case.

Iingenelo zeNitriding kunye neNitrocarburizing ziquka ukomelela okuphuculweyo kunye nokumelana nokuguguleka okungcono kunye nokubola

Ukufaka i-nitriding kunye ne-nitrocarburizing kusetyenziswa kwiigiya, izikrufu, izipringi, ii-crankshafts kunye nee-camshafts, phakathi kwezinye.

Iifurnace zicetyiswa ukuba zisetyenziswe xa kugalelwa i-carburizing kunye ne-nitriding.
